Yu-Na has unbelievably been boisted to the top in some events.... she has gone from having strong programs with ordinary PCS scores (ordinary for her... high 50s), to skating another competition and having her PCS scores somehow boosted 10 points even though it's the same program and no real reason to have it happen (see Worlds).
Let's look at Skate America... Yu-Na only gets off 3 clean triples, underrotates her combo and gets a total of 111.70. Rachael Flatt skates a clean 7 triple program, including a 3F+3T combination and only comes in ahead of Yu-Na by under 5 points with 116.11. Sure, Rachael doesn't have the artistic skills of Yu-Na, not even close.... but Yu-Na shouldn't be allowed to pop and underrotate all but 3 of her triple jumps and put up a score that most skaters can't beat clean. Everyone says Mao's PCS were affected by her mistakes... what about Yu-Na's PCS scores here? This program was FAR from perfect... but it still won Gold at SA.
IMHO, Skate America proves that Yu-Na definitely will need her 3Lz+3T in the SP to really secure Gold... if she has a great short, she has quite a bit of room for falls and errors in the LP. So it will either all come down to the SP...
OR
The judges will wind up giving "strange" PCS scores like they did at the Mens competition (Plushenko and Lysacek with the same PCS? hardly.), but if a strong program winds up meaning good PCS scores again, that OGM has way more possible takers than most people are probably thinking (my money would be on either Joannie or Miki if they skate clean... possibly even Rachael though I don't want that to happen).
As for Mao, I don't know WHAT they were thinking with her LP music. Mao's Bells of Moscow is really just the first few measures of Rachmoninov's absurdly famous Prelude in C Sharp Minor, Op. 3 No. 2 (which I'm quite mad she didn't use the whole thing... it was my audition piece for a conservatory when I was young and it worked for me then, it can work for her now lol

). If she wanted to use this song, she should have used the WHOLE piece, since it has beautiful changes in pace and mood that would fit other sections of her program much better than the same repetitive bars. If anyone wants to hear the whole piece of music, here is a link to Rachmaninov actually playing it:
